Practical Engineering | Redefining the Kilogram with the DIY Watt Balance @PracticalEngineeringChannel | Uploaded September 2016 | Updated October 2024, 5 days ago.
Mass is a challenging concept to tie down, yet it is one of the most crucial measurements in our world. Since the 1800's, we've used a physical artifact as a standard for mass calibration across the world. Within the next few years, that will all change because of this ingenious device: the watt balance.
